public class IXT2_dateyearmonthen
extends IXTForwardBackwardDate

Transforms English date in the format "YY(YY)*Mon(th)" into W3C/ISO date standard "YYYY-MM" format. Two-digit years are assumed to fall between 2000 and 2099 and one-digit years to fall between 2000 and 2009. When a date contains several month names (e.g. "1969, January, March and April"), the transform must match the last occurrence.
